✦ Synopsis

The amelioration of ªhot spotsº in a molecule through specific molecular association is a general chemical principle, which has been recently highlighted as a driving force for ªsupramolecularº reactions. [1] The instability of unpaired radicals, uncoordinated metal ions and ligands, and unasso-evidence for positive cooperativity among the metal binding sites in 1-Cu 3 .

Thus, metal-binding properties of 1 and the high symmetry of 1-Cu 3 illustrate a high degree of control over the degree and regularity of molecular entwinement. In combination with an appropriate macrocyclization method, the stage is set for the directed synthesis of complex topological stereoisomers of high symmetry, specifically, a molecular trefoil knot.
